为了研究低周循环往复荷载作用下GFRP(glass fiber reinforced polymer)-钢管-混凝构件的力学性能以及对比CFRP(carbon fiber reinforced polymer)-钢管-混凝土构件的性能差异,对尺寸相同而加固方式不同的圆形截面FRP(GFRP、CFRP)-钢管-混凝土试件进行了拟静力试验,荷载采用轴压、双向弯曲的组合来模拟地震动力.结果表明:FRP(GFRP、CFRP)的加固可以有效地提高构件抗动态弯曲的能力；GFRP-钢管-混凝土构件延性高于相同情况下CFRP -钢管-混凝土构件；与普通钢管-混凝土相比,环向、纵向和双向包裹的GFRP-钢管-混凝土构件的耗能系数分别提高2.0％、7.0％和12.7％,而CFRP-钢管-混凝土分别提高2.0％、5.8％和6.7％.
